Hence, epoxywelwitschene (4) was tested in a dose-dependent manner and the effects were presented as the relative ATPase activity, in which the stimulated vanadate-sensitive ATPase activity is taken as 100% and the base line vanadate-sensitive ATPase activity as 0%.
Of note, as already mentioned, tyrosine modifications at the level of the [beta] subunit of ATP synthase have been described to be modulatory of the catalytic ATPase activity in the presence of ROS/RNS [108,109], even if their direct involvement in ALS remains to be addressed.
